Cloud Security Survey 2013: Extent of Cloud Deployment (Part 2)

This is part 2 of a 3 part series on a cloud security survey recently conducted by CloudPassage. The survey looks at the actual adoption of cloud computing, both private and public clouds, what cloud benefits are most important to businesses, what security challenges are the biggest pain points  and so on.

We looked at the percentage of companies that are deploying private versus public clouds in part 1 of this blog series. But how much do companies rely on private and public clouds once they have implemented them? How many server instances have they deployed? What percentage of their new versus existing applications have they deployed in the cloud? These are the questions we will answer here.

We saw in the first blog post that overall implementation of private and public clouds is relatively even. However, the extent of server deployment in these two models differs. See below.

Looking at the results for “All” companies, of those that have implemented a private cloud, most have deployed over 100 server instances. However, with public cloud, most have deployed less than 25 servers. Part of this difference can be explained because enterprises deploy more private clouds and they have more server instances. And slightly more SMB organizations deploy public clouds and they have fewer server instances. (Deployment of private vs. public clouds is discussed in the first blog post of this series).

Looking at the split between enterprises and SMB organizations within each cloud model, the results are relatively intuitive. In both private and public clouds, enterprises were more likely to deploy larger numbers of server instances in the cloud than SMBs.

In addition to the number of servers, the survey also asked about the level of cloud deployment for new versus existing applications. With private clouds, the most number of responses were at either end of the deployment  spectrum – with about a third under 20% deployed and another third 90-100% deployed.

However, those that deployed public clouds were more likely to completely deploy their existing and new applications in the cloud. (Over half of all organizations deployed over 80% of new applications to the public cloud.)  The trend will continue and grow as the list of organizations that are “born” in the public cloud grows.

In our next blog post in this series, we’ll look at organizations’ concerns about applying traditional security in private and public clouds.
